With the rapid development of computer networks, especially with the introduction of the Semantic Web
perspective, the problem of trust computation in the network has become an important research part of current computer
system theoretical. In this paper, according the information properties of the Semantic Web and interact between nodes,
the definition semantic trust as content trust of information and the node trust between the nodes of two parts. By
Calculate the content of the trust of information and the trust between nodes, then get the final credibility num of
information in semantic web. In this paper , we are improve the computation algorithm of the node trust .Finally,
stimulations and analyses show that the improved algorithm can effectively improve the trust of information more
accurately.
